of the arms of the 

 Cross. The bright 

 star, Deneb, is in the 

 tail of the swan, and 

 its neck is stretched for- 

 ward as if it were headed 

 for a warmer climate. 



Lyra, the Lyre. This 

 constellation is next to 

 Cygnus and west of it. 

 In it is one very bright 

 star, called Alpha 

 Lyrae, or Vega. This 

 star is 52 degrees from 

 Polaris. Throughout 

 the summer it is one 

 of the most attractive 

 stars in the heavens. 

 It is visible also in fall 



and winter, but is not likely to be seen in the evening in 

 February or March. It is near the spot in the heavens 

 toward which the sun, with the earth and all the other 

 bodies of the solar system, are moving (page 210). 



Pegasus. If you look about 40 degrees southeast of 

 the Northern Cross, you will see a large square, known 

 as the Great Square of Pegasus. The stars at the corners 

 are of the second magnitude, and the sides are about 

 15 degrees long. Pegasus was a winged horse. The 

 stars of the square lie in the body of the horse, but no 

 hind quarters are to be seen. The square may be seen 

 in the evening throughout the latter half of the year. 



FIG. 129. Cygnus, the Swan. The bright 

 star, Deneb, is in the back part of the 

 body. It will help the reader easily to locate 

 this constellation if he holds the book over 

 his head and looks at the picture from be- 

 low, while he faces the north.
